Both Zenith Carb damper/pistons not lifting
Posted: Sun Nov 19, 2017 3:19 am
Hi All,
Wondering if anyone has any idea why the dampers/pistons on both carbs(factory zeniths) will not lift ?
I have checked diaphrams, look fine.
While running, if i manually open the dampers, with a screwdriver, it roars into life and sounds great as it should, so they are not stuck..
Engine will start, and run, but is only getting air in through the breather ports that are normally plumbed into the rocker covers.. if they are connected to rockercover, engine doesnt get enough air and dies.
It will drive at upto 65kmh but is obviously very restricted..
It was running fine previously, then after afew months of being parked, it was hard to start. Replaced the batteries, checked plugs, leads ect. Now have it started again, but running like a sack, and find no lifting action in both carbs!?
Cheers for any help..
